Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed July 22, 1916. Serial No. 110,752.

To all whom it may concern:

Be it known that I, CECIL I-IAMELIN TAY- LOR, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Radiators, and declare the following to be a full, clear, and exact description of the same such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to radiators for automobiles and an object of my improvements is to provide an improved radiator in which the expansion and contraction due to changes in temperature shall be uniform.

I secure this object in the device illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a radiator embodying my invention, partly broken away to show the interior construction.

Fig. 2 is a plan View of the same also partly broken away on the lines B-B, B-B, Fig. 1.

Fig. 3 is a plan view of a washer employed in the apparatus shown in the other figures.

Fig. 4 is a sectional elevation of a radiator embodying my invention showing the construction and connection with the core.

a is the bottom, and b the top header, or reservoir. d, d are spacers or standards between the ends of the headers a and b. The headers and spacers may be made of cast iron and together constitute the frame of the radiator.

c is the core, or filler, secured between the headers a and b, and between the spacers d, cl.

The spacers d, d are hollow and open to the interior of the headers a and b so that the water can circulate through them from said headers independent of the circulation through the core.

1'', f are bolts, or screw-threaded rods, extending through apertures in the headers a and b and passing through the interior of the spacers d, d. Nuts 6, e, e, e, are screwed upon the end of the rods, or bolts f, and tightened up to secure the frame together.

Between the ends of the header 7) and each of the spacers d, d is placed a washer g. This washer has a graduated aperture 9 formed in it to regulate the rate at which water is circulated through the spacers.

Heretofore in radiators having, the frame and core construction the spacers (Z, (Z and core 0 have expanded at different rates with an increase of temperature, or the temperature has changed at a different rate in such spacers and in the core. This has caused strains upon the joints which have caused leakage.

In the above described construction the water circulates through the core and also through the spacers cl, d in contact with the wall of said spacers and with the binding bolts 7", f. The aperture 9 through the washer g is made of such a size that the rate at which the water passes through the spacers shall be regulated so that the expansion of these bolts and spacers shall be uniform with the expansion of the core and no strains are occasioned by unequal expansion. Different constructions of the core will require different sized apertures through the washer. The proper size of aperture for a given construction will be ascertained from experience.

What I claim is:

1. In a radiator, an upper and a lower 7 reservoir, a hollow spacer extending between said reservoirs and communicating with their interiors, and a core between said reservoirs communicating with the interiors of the same independent of the spacer, and means for establishing a rate of flow of water through said spacer relative to that through the core, so that the spacer and core shall expand and contract proportionally owing to their change of temperature under the influence of the circulating water.

2. In a radiator, an upper and a lower reservoir, a hollow spacer extending between said reservoirs and communicating With their interiors, and a core between said reservoirs communicating with the interiors of the same independent of the spacer, and means for establishing a rate of flow of water through said spacer relative to that through the core, and a bolt extending through said spacer engaging said reservoirs so that said bolt, spacer and core shall expand and contract proportionally owing to their change of temperature under the influence of the circulating water.

3. In a radiator, an upper and a lower reservoir, a hollow spacer extending between said reservoirs and communicating with their interiors, and a core between said reservoirs communicating with the interiors of the same independent of the spacer, the area of the passage through said spacer being such as to establish a rate of fiow of water therethrough relative to that through the.

core, so that the spacer and core shall expand and contract proportionally owing to 10 their change of temperature under the influence of the circulating water.

In testimony whereof I sign this specification.
